edge2vec: Representation learning using edge semantics for biomedical knowledge discovery

Understand

Representation learning provides new and powerful graph analytical approaches and tools for the highly valued data science challenge of mining knowledge graphs.

• Since previous graph analytical methods have mostly focused on homogeneous graphs, an important current challenge is extending this methodology for richly heterogeneous graphs and knowledge domains.
• The biomedical sciences are such a domain, reflecting the complexity of biology, with entities such as genes, proteins, drugs, diseases, and phenotypes, and relationships such as gene co-expression, biochemical regulation, and biomolecular inhibition or activation.
• Therefore, the semantics of edges and nodes are critical for representation learning and knowledge discovery in real world biomedical problems.
